GE IS200DSVOH2B Simplex DIN-rail Mounted Servo Terminal Board

د.إ8,888.00

GE IS200DSVOH2B Simplex DIN-rail Mounted Servo Terminal Board (DSVO) is a specialized Printed Circuit Board (PCB) used in the GE Speedtronic Mark VI Turbine Control System.1

It serves as a compact, non-redundant (Simplex) field-wiring interface for electro-hydraulic servo mechanisms, which are used to control critical turbine valves (like fuel or steam valves).

⚙️ Key Functions and Features

The DSVO board’s main role is to provide the necessary I/O connections and signal conditioning between the field devices and the main control system processor board, specifically the VSVO VME Servo Control Board.2

Feature Details
System GE Mark VI Speedtronic Turbine Control System
Function Simplex (Non-redundant) Servo Terminal Board
Servo Outputs Provides connections for two servo valve outputs used to drive the coils of electro-hydraulic servo valves.
Position Feedback Accommodates up to six LVDT (Linear Variable Differential Transformer) position sensors for accurate valve position feedback.
Rate Inputs Includes two active pulse rate inputs often used for flow measurement or speed signals.
Current Control Servo coil currents are jumper-selectable, typically ranging from 10 to 120 mA.
Mounting Designed for DIN-rail mounting using Euro-Block terminals, which allows for vertical stacking to conserve cabinet space.
Processor Interface Connects to the VSVO board via two cables (a 37-pin and a 15-pin).

🛡️ H2B Revision Significance

The H2B revision of the DSVO board is functionally similar to previous revisions (like the H1A and H1B) but carries a key distinction related to its certification for use in hazardous locations:3

  • Hazardous Location Certification: The IS200DSVOH2B is certified by UL to UL-1604 Class 1, Groups A and B, Temperature Class T4, Division 2 standards.4
  • Previous Version: The IS200DSVOH1B (the direct replacement for the H1A) did not carry this specific hazardous location certification.

This certification makes the H2B model suitable for installation in control panels located in certain industrial areas where flammable gases or vapors may occasionally be present. The board is also typically protected by a conformal coating for enhanced environmental durability.5
